It's hard to say exactly when this slide happened. I had eyes on this slope on Tuesday 11-29 and it had not avalanched. Moderate to Strong Southerly winds have been loading this slope since 7 inches of snow fell Monday night into Tuesday morning. The bed surface was starting to fill in with wind drifted snow. The debris was hard, but not frozen solid. We probed an average of 120cm in the deepest part of the debris pile.

Ultimately this slope got enough of a load from wind drifted snow to overburden the weak layer of buried facets.
